The reason why it sounds like someone is periodically transmitting is because it's only interfering when someone keys up. If no one transmits the channel is just quiet, forever, as it should be, when no one is transmitting. But, if dispatch or a unit keys up, boom, interference. So it's not like...
Sorry, forgot to mention the reason why I think that it's two repeaters, is because it sounds like the interference has a "hang-timer" when the carrier drops.
My local police department has been having this issue for a while on their main dispatch channel and I was able to catch it on my scanner. I'm not an expert, but to me it sounds like two repeaters transmitting at the same time. Here's the audio clip: Whyp - Free Audio Sharing for Everyone
What...
Very interesting, thanks for the clarification on that. As a side note, I was listening to Palo Alto PD last night and they were broadcasting PII on the newly unencrypted channel. Seems like they are no longer complying with that agreement with CLETS.
I don't know why you are so hung up on CLETS data and PII being broadcasted unencrypted. My local communications center does this on the daily. Santa Cruz Regional 911. They are all analog, and constantly run DL numbers/name and DOB over the air for everyone to hear and it's never been a problem.
Sounds like the channel you are using to talk to dispatch is programmed to be simplex on the repeater output frequency only. So it's just you talking straight to dispatch, not going through the repeater. Your transmission is not being rebroadcasted to everyone else, hence why no one else can...
Interestingly, in my KPG-111D it shows +180 degree phase shift, which is what Kenwood uses by default, but for the 120 degree phase shift, it shows + or - 120, not sure which one Moto actually uses.
Ok, So I happened to be in the downtown area of this particular county again and was monitoring when a pursuit ended right where my car was parked. So obviously I couldn't go anywhere and was walking around being a snoop while I waited for the officers to get out of the way and I glanced at...
Ahhhh, I see. That makes a lot of sense. In that Motorola clip I initially provided, you can definitely hear that Automatic Gain Control and heavy compression in effect, hence why the person speaking, does sound quite nasally. And exactly the opposite with the Kenwood's more deep low's and such...
Absolutely! There's just something about that Motorola that sounds really good to my ears. And I agree with you 100%. The Harris XG-100M and XG-100P sound almost indistinguishable from a Motorola. Harris did a great job with those radios.
And sorry guys, I know I'm probably coming across as a Motorola Fanboy or whatever, but this again just my personal opinion and I'm not invalidating any of yours. I can totally see where you guys are coming from as well.
Companding! It's been a while since I programmed a Motorola, I remember that "companding" mode is one of the settings that really effected how the radio processed the audio. If I remember correctly, that's the sort compressor filter that I mentioned earlier, probably not what it's actually...
But I'm not imagining it though right? Those Motorola's sound miles better than those Kenwoods, disregarding the subpar programming, as they stand right now, the Kenwood's sound terrible.
